I don't know if it's because its early access so the attitude rates or choices are different than how they'll be at launch but I've been doing a co-op run with a friend and we've accidentally gotten really flirty/romantic lines from the companions multiple times.

We weren't trying, we weren't looking for it, and neither of us are interested in romancing fictional characters at all. It's incredibly off putting if you're not interested in it and it's not something you can "just ignore" when a character you're getting to know suddenly starts acting like they want to tickle your pickle out of no where.

I'd just love a setting to just.. turn it off. Platonic mode.
